Prätorius expresses himself regarding the Viola da Gamba as follows: “Violas, viols, and violuntzes[14] are of two kinds—1. Viole de gamba; 2. Viole de braccio (or de brazzio)—and the former is so called from having been held between the legs; for gamba is an Italian word and means a leg; le gambe, the legs. And since they have much larger bodies and, on account of the length of the neck, have strings of a much longer tension, they produce a mellower resonance than others, ‘di braccio,’ which are held on the arm. The two kinds are distinguished by town musicians: the viole de gamba by the name of violas: the viole ‘di braccio’ (among which Prätorius includes violins) by the name of fiddles or pollish fiddles....
“The Violes de Gamba have six strings and are tuned in fourths and in the middle a third, exactly like the six-stringed lute. Englishmen when they play them alone sometimes tune them a fourth, sometimes a fifth lower, so that the lowest strings are tuned—the bass to D, the tenor and alto to A, and the canto to E. On other occasions each one (reckoning by the chamber-pitch)[15] a fifth lower—as, for example, the bass to G G, the tenor and alto to D, the canto to A; and tuning in this manner produces much more agreeable, grander, and more majestic harmonies than when the instruments are at the usual pitch.”
What Prätorius says regarding the mode and way of English viol-tuning is supplemented by Mersennus in his “Harmonie Universelle” (1636-37). This author says: “Il faut remarquer que les Anglois ioüent ordinairement leurs pièces un ton plus bas que les Français, afin d’entendre l’harmonie plus douce et plus charmante, et conséquemment que leur sixiesme chorde à vuide fait le C sol au lieu que la nostre fait le D re sol.”
The pitch then in England was a varying one, though the series of intervals borrowed from the lute, to which the gamba like the bass viol was tuned, were those which commonly prevailed.
In other respects, Mersennus gives no more explicit directions for the handling of the Viola da Gamba than Prätorius. He does not use this name for the instrument in question, but calls it “Basse de Viole.” The French designation, “Viole de jambe,” corresponding to the Italian name, appears consequently to have been in vogue later and to have been generally little used.
Like Gerle’s “great fiddle” (Basso di Viola), the Viola da Gamba had also as a rule seven frets on the fingerboard like the lute, for fixing the tones and semitones.
The gamba was played in various ways, and used for a variety of musical purposes, as a solo instrument, as well as in orchestral performances, and as an accompaniment to singing. The way in which it was valued during the first half of the seventeenth century as an obbligato accompaniment to singing, may be seen from the preface to Heinrich Schütz’s “Historia of the joyful and victorious resurrection of our only Saviour,” and so on, published in 1623. It is there said, after Schütz has named the instruments which are to accompany the parts of the Evangelists: “But when it can be done it is better that the organ and everything else should be left out and instead of these only four Viole di Gamba (which must also be present), should be used to accompany the parts of the Evangelists.”
“It will, however, be necessary that the four viols should be thoroughly ‘practised’ with the part of the Evangelist in the following manner: The Evangelist takes his part to himself, and recites it straight through without any fixed time, just as it seems correct to him, but not holding longer on one syllable than is customary in ordinary slow and distinct speaking. The violas must not mark any particular time, but only pay attention to the words recited by the Evangelist, and to their parts written below the ‘falso-bordone’ and so doing they cannot go wrong. A viola may also ‘passegiren’ amongst the others, as is usual with the falso-bordone,[16] and this gives a good effect.”
It appears from the explanation that the gambas were used to support the harmonies of recitatives. The “passegiren” suggested by Schütz of one of the accompanying violas was nothing else than the usual improvised ornamental colorature or diminuendos used at that time and up to the eighteenth century.[17]
